LWRCI UCIW Ultra-compact stock

Compact AR non-SBR build

https://www.lwrci.com/p-361-uciw-ultra-compact-stock.aspx

Does anyone have experience with the LWRCI UCIW Ultra-compact stock? I'm looking to do a non-sbr compact lightweight 14.5" build and have been looking at the NEA stock, but am looking for cheaper option.

I have one and I love it. Get some extra action/buffer springs from LWRC or get some superior shooting solutions flaw wire springs for spares (this is what I did). No need to clip the spring it works on the UCIW shorter buffer.

Heavy Buffers now makes Heavy Buffers for it if that's your thing.

A Syrac Ordnance or SLR Rifleworks Adjustable Detent Gas Block really makes these things work sweet together for a D.I. setup.


FYI if you use a 9mm conversion the stock UCIW buffer wont be heavy enough and its too short. too much bolt travel on a 9mm AR and you break the bolt catch.

You can use a regular carbine 9mm or heavy buffer for a 9mm setup and get sufficient bolt travel with a flat wire spring. Heavy Buffers is also working on a 9mm H Buffer for the UCIW.

FWIW, it on my host 9mm AR15 SBR mostly. Its a 4.5" Barrel and a UCIW stock.

I also use it on my 13.75" 5.56 with a SLR Gas Block.

Thanks for the info! I'd been tossing around the idea of the NEA compact stock, but there are a few things about it which have been holding me back like price, the proprietary carrier/buffer and the issues that may cause with trouble-shooting with buffer/springs, having a much more complicated field-striping process due to the carrier/buffer, etc.

The UCIW seems like a better option.

I just checked out Syrac and SLR... Very slick! I take it they are worth the premium if you are recommending them.

Do you have a 14.5" LW barrel you would recommend?

BCM LW Mid Gas and a SLR Melonited .625 Gas Block. Get the GB pinned and you'll have a bad ass setup.

There you go having me spend the money I'd save over the NEA stock.

Should have funds together to start acquiring next week.

Its a wise reason to save The SLR GB also makes is easy to adjust gas when adding a suppressor.

Be aware of the access you need when choosing a rail. a long ball tipped allen tool will reach the adjuster easy. They sell them on the SLR site.

I attached mine to the rail so its always there. I also have a range rod on the rail as well to clear stuck casings.

I have a factory UCIW. The buffer that comes in the kit is a little more polished than their original ones. Below are some pics comparing standard buffer and receiver extensions to the ones used on the UCIW. Please note that LWRCI has since polished the UCIW stock combo and that's what you'll get when you order it from them. Compared are also the size of a VLTOR IMOD to LWRCI compact stock and LWRCI compact vs. ultra-compact stocks.

Thanks for all the info... do you have pics of the allen tool/range rod rail setup? Sounds pretty slick.

Epic pics... totally what I was looking for!

SBR for the 13.75"? or what muzzle device are you using for it otherwise?

One of the uppers is a Noveske 13.75" Mid Gas with a YHM Q.D. Mount. Yes, I have 2 AR lowers that are SBR (Form 1).

I don't use Brakes anymore as they are just too darn loud for practical use IMO.

 

[Calengor]

Ahh. I've been pondering a 13.7" with pinned B.E. Meyers 249F and was curious if you had that setup and if so how you liked it.

[Devil Dog]

It isbon their main site but the ad "scrolls" so you have to wait for it to appear.
IIRC, the code for use at chexkout is icdaddy2014

NICE!

I would go with a SSA-E Trigger.

BArrel choice is great too. An alternative is a Ranier SS 13.7" barrel with a YHM 6.62 Q.D. mount threaded to 1/2-28. Its not a listed mount but they make it. That combo pinned and welded is 16.1". The 7.62 Shield Mount is an option too.

The 3.7" barrel just looks more compact with a 12.5" rail.

Either way its a sweet build.

Chad. I always thought that the longer spring helped contribute to a more reliable rifle. Also, won't a longer spring with more coils provide a smoother feeling rifle?

I've never shot an AR with one of these compact kits but from what I've shot, I can tell a difference between a rifle extension or an A5 extension versus a carbine extension. On a 16" mid, the rifle and A5 felt smoother and softer if that makes any sense.

So, do these ultra compact springs/buffers sharpen the recoil impulse and/or decrease reliability? I'd like to put one on a 14.5" mid-length but I don't want to sacrifice reliability and or an already very soft shooting rifle.
